We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).

rtoz (2530056) writes "A group of scientists in California have successfully created eye drops that temporarily enable night vision.

They use mixture of Insulin and a chemical known as "Ce6" (Chlorin e6) as eye drop for getting the night vision. It allows the user to view the objects clearly up to 50 meters in darkness.

This chemical "Ce6" is found in some deep-sea fish and is often used to treat cancer and night blindness.

The Ce6 solution will start work in as little as one hour after getting injected into eyes using micropippette. And the Night vision effect will be lasting for “many hours” afterwards, and the test subject's eyesight will become normal the next day.

The organisation "Science for the Masses" has released a paper that detailed the experiment in their website."

rtoz (2530056) writes "Scientists report in the journal ACS Applied Materials & Interfacesthat they successfully used compounds from green tea to help image cancer tumors in mice.
Using a simple, one-step process, the researchers coated iron-oxide nanoparticles with green-tea compounds called catechins and administered them to mice with cancer. MRIs demonstrated that the novel imaging agents gathered in tumor cells and showed a strong contrast from surrounding non-tumor cells. The researchers conclude that the catechin-coated nanoparticles are promising candidates for use in MRIs and related applications."Link to Original Source

rtoz (2530056) writes "The Scientists at University of Washington and Stanford University built a new nanometer-sized laser which uses a tungsten-based semiconductor only three atoms thick as the “gain material” that emits light.

The UW nanolaser is energy efficient, easy to build and compatible with existing electronics. This technology is described in a paper published in the March 16 online edition of Nature.Compared to other nanolaser designs, that makes them difficult to build and integrate with modern electrical circuits and computing technologies.But this UW’s nanolaser can be easily fabricated to work with silicon components common in modern electronics."

rtoz (2530056) writes "Facebook Founder Mark Zuckerberg has posted a status update in his Facebook account about the Threats he had faced from extremist from Pakistan.
In his Facebook status message he says,

few years ago, an extremist in Pakistan fought to have me sentenced to death because Facebook refused to ban content about Mohammed that offended him.
We stood up for this because different voices — even if they’re sometimes offensive — can make the world a better and more interesting place.
Facebook has always been a place where people across the world share their views and ideas. We follow the laws in each country, but we never let one country or group of people dictate what people can share across the world.

Powerful new NVIDIA Maxwell architecture, 256 GPU cores, a 64-bit CPU, unbeatable 4K video capabilities, and more power-efficient performance than its predecessor make it perfect for even the most challenging mobile and automotive applications."

In times of disaster or crisis, people turn to Facebook to check on loved ones and get updates.

During a major disaster, Safety Check will help you:

Let friends and family know you’re safe
Check on others in the affected area
Mark your friends as safe

When the tool is activated after a natural disaster and if you’re in the affected area, you’ll receive a Facebook notification asking if you’re safe.

Facebook will determine your location by looking at the city you have listed in your profile, your last location if you’ve opted in to the Nearby Friends product, and the city where you are using the internet.

If you’re safe, you can select “I’m Safe” and a notification and News Feed story will be generated with your update. Your friends can also mark you as safe."

The Korea Hydro and Nuclear Power Co. (KHNP) manually stopped operation of the Gori-2 nuclear power plant in Busan for safety reason due to excessive water in the area.

There were no signs of a radiation leak or of any immediate risk, the KHNP said. It was the first time in history that a Korean nuclear reactor had been shut down because of rain. The Gori-2 reactor has been in operation since July 1983."

A twitter account named “Lizard Squad” is claiming responsibility for this hacking activity.Previously they have brought down Sony’s PlayStation Network, which enables gamers to play each other online and access content.It was hit by a so-called denial of service after it was overwhelmed by hackers driving artificially high traffic to its servers.

And, a flight carrying John Smedley, the president of Sony’s online entertainment unit was diverted for a security issue."

rtoz (2530056) writes "Google has just announced a new processor for Project Ara. The mobile Rockchip SoC will function as an applications processor, without requiring a bridge chip. A prototype of the phone with the Rockchip CPU, will be available early next year.

Via Google+ post, the Project Ara team Head Paul Eremenko says “We view this Rockchip processor as a trailblazer for our vision of a modular architecture where the processor is a node on a network with a single, universal interface--free from also serving as the network hub for all of the mobile device’s peripherals.”"

rtoz (2530056) writes "A team at MIT has now developed a model to evaluate the performance and optimal dimensions of large PRO systems. In general, the researchers found that the larger a system’s membrane, the more power can be produced — but only up to a point. Interestingly, 95 percent of a system’s maximum power output can be generated using only half or less of the maximum membrane area.

A PRO system could potentially power a coastal wastewater-treatment plant by taking in seawater and combining it with treated wastewater to produce renewable energy."
